Threeshrew was a daughter of Log-a-Log Togey in the Guosim and was widely known for her dancing and singing abilities. She was the sister of Oneshrew, Twoshrew, Fourshrew, Fiveshrew and Eightshrew. She was believed to be the twin of Fourshrew, her brother. The reason for her odd name was that her father had many children, and he could not be bothered to give them real names.
